FREQUENTLY ASKED QUESTIONS
- QUESTION: At certain times of the year I need to run portable troughs in my paddocks, is it possible to run these off my existing Super-Flo valve?
- ANSWER: Yes, the Super-Flo Trough Valve incorporates a 25mm (1”) thread on the valve outlet that can utilised the spare adaptors that come with the valve to enable to attach any number of poly pipe fittings to the Super-Flo trough Valve. This off take can be used for any number of farm applications.
- QUESTION: At present, I get valve bounce in my troughs, will the Super-Flo and Max-Flo valve stop this?
- ANSWER: Yes, valve bounce is created from high flows at high pressures, because the Hansen Super-Flo or Max-Flo valve delivers higher flows than other valves; it will effectively reduce line pressure which in return will reduce the incidences of this problem by also reducing water hammer.
- QUESTION: At present I have noticed some shuddering and noise in my pipelines when my pump starts and stops, will your valve stop this?
- ANSWER: Yes, this is called water hammer, the Hansen Max-Flo Valve was designed to open and close slower than other valves effectively varying the flows at these times to minimise the chance of water hammer.
- QUESTION: Can I use Hansen True Fit Fittings under driveways, paths and foundations?
- ANSWER: Hansen does NOT recommend the use of any Hansen True Fit Fittings under any driveways, paths or foundations.
- QUESTION: Can I use my Hansen fittings with my swimming pool/spa pool set up?
- ANSWER: No, as the high concentration of chlorine used in the water for pools will attack the material. The fitting material is only suitable for use with domestic water. Hansen products that are used in this application will not be covered by our Hansen Warranty.
- QUESTION: Can I use the Hansen Max-Flo Valve as a top entry valve with an air gap?
- ANSWER: Yes, the Hansen Max-Flo Valve can be installed at the top, side or bottom entry as all components come with each valve.
- QUESTION: Can I use these fittings with metal fittings?
- ANSWER: Yes. For more information on installation tips, kindly refer to the installation instructions.
- QUESTION: Do I need to support my fittings?
- ANSWER: Yes. All pipe work must be adequately supported.
- QUESTION: Does this fitting carry the Hansen Warranty?
- ANSWER: Yes, all Hansen manufactured products carries Hansen Warranty.
For more information about the Hansen Warranty, please visit the Legal Information link in the footer part of the Hansen’s website.
- QUESTION: For years now, I have had problems with filling my tanks as my water supply can get very dirty at times. I believe I have purchased every valve on the market and all have let me down at some point. Will the Hansen Leveller Valve finally fix my problem?
- ANSWER: Yes, the range of HiFlo Valves are designed to handle dirty water. The Hansen Leveller Valve, which is based on our diaphragm valves, is unique and it has a pin that cleans the pilot hole in the diaphragm every time it opens and closes. In addition to that, the gap between the diaphragm and the valve body when opened is a huge 14mm further reducing potential blockages.
- QUESTION: How tight should I tighten my Hansen threaded fittings?
- ANSWER: Do not over tighten. The right way to assemble a threaded fitting is hand tight plus one to two turns – no more! For more information on installation tips refer to the installation instructions.
- QUESTION: I have a compact float valve in a header tank. The flow is too low into the tank and won’t keep up with our requirements. I can’t fit a larger valve into this tank, if I replace it with a Hansen Fast-Flo Valve will the flow be any better?
- ANSWER: Yes, the Fast-Flo valve has the highest flow of any valve in its class/size. At 500 kPa (73psi), it will deliver 56 l/min.
- QUESTION: I have a header tank in my house that is very noisy while filling, will the Hansen Fast-Flo or the Mini Fast-Flo valve be any quieter?
- ANSWER: The noise while the tank is filling is caused by the high velocity of the water from the valve outlet into the tank. The valve outlet doubles as a spigot so it can be attached as a length of hose to allow the flow to be placed onto the bottom of the tank eliminating this noise.
- QUESTION: I have found the rubber seats in the compact trough valves I am using don’t last very long, does the Hansen Fast-Flo or Mini Fast-Flo valve use the same rubber seat?
- ANSWER: No, the seat we use in Hansen Float Valves are urethane which is a very durable and hard material. The seal is also reversible if a foreign body should damage it.
- QUESTION: I have noticed my pump switching on and off rapidly at times, will your leveller valve stop this?
- ANSWER: Yes, this is called cycling and can drastically reduce the life of the pump. The Hansen Leveller Valve is designed to control the pump safely by eliminating pump cycling and providing an adjustable water differential depth in the tank.
- QUESTION: I have problems with having to constantly clean my valves as my water supply can get dirty at times, how will the Hansen Max-Flo Valve handle these conditions? also, the Hansen Super-Flo Valve?
- ANSWER: The patent pending “Self Cleaning Pilot” will increase durability and suitability in dirty water situations. The Hansen Super-Flo valve is designed to work in either clean or dirty water situations.
- QUESTION: I only irrigate from my tank at night and have a time on my bore pump. It will only fill my tank at night when I’m irrigating but I still find my bore pump is cycling when I’m irrigating. Will the Hansen Leveller Valve help in this situation?
- ANSWER: Yes, the reservoir valve being used at the moment is only supplying a flow close to the irrigation demand, with the Hansen Leveller Valve the flow delivery will be much higher and will allow the bore pump to run for less time as well as setting a differential in the tank to enable the pump to shut off for sensible periods.
- QUESTION: In my dairy shed at peak water demand times, I find my pump is cycling. As demand increases, they run continuously and often can’t keep up, resulting in more water in troughs and other areas in my shed. Will your Leveller Valve fix this issue?
- ANSWER: Yes, as long as the pumps are sized correctly to cover the peak demand, the Hansen Leveller Valve will help by delivering a much higher flow at much lower pressure (e.g. 400kPa (58 psi) = 772 l/min (170 gpm)).
- QUESTION: My rain water supply can get very dirty at times. Can the Rain Relief Valve cope with dirty water?
- ANSWER: Yes, both the Slo-Flo and Rapid-Flo Rain Relief Valves are designed to handle dirty water.
- QUESTION: My troughs have both 20mm & 25mm threaded inlets, does your Hansen Max-Flo and Super-Flo Valve come in both sizes?
- ANSWER: Yes, the Hansen Max-Flo and Super-Flo Valve comes with the required components to install in 20mm or 25mm threaded inlets. This means to only buy one valve for all sized inlets.
- QUESTION: The pressure at my compact trough is quite high and the compact float valves I have used either don’t last very long or they don’t shut off properly. Will the Hansen Mini Fast-Flo or Fast-Flo Valve work with high pressure?
- ANSWER: Yes, both the Mino Fast-Flo and Fast-Flo Valve has the arm pivot point positioned to allow closing at pressures up to 12 bar (174psi). And for Fast-Flo Valve with a 115mm float attached.
- QUESTION: The valves I have a present have a tendency to jam open or closed costing me time and either a bog around my trough or no available water for my stock, will your valves stop this problem?
- ANSWER: Yes, the Hansen Super-Flo valve has a new patent pending “Slipper Fit Piston” design seal assembly to minimise this kind of problem.
- QUESTION: What is the difference between the Rain Relief Valve and the Leveller Valve?
- ANSWER: The Leveller Valve opens when a pre-defined minimum water level is reached and will fill the entire tank. The Rain Relief Valve will only supplement the tank with either 50mm or 100mm of water, depending on the float orientation.
- QUESTION: What is the difference between the Slo-Flo Rain Relief Valve and the Rapid-Flo Rain Relief Valve?
- ANSWER: The Rapid-Flo and Slo-Flo Rain Relief Valves are essentially the same valve. The key difference between them is that the Rapid-Flo valve is capable of functioning at full flow rate whereas the Slo-Flo valve is restricted to 2 l/min to conform to the Sydney Water Guidelines.
- QUESTION: What pressure can I run my Hansen Max-Flo or Super-Flo Valve at?
- ANSWER: Both will operate from 0.2 bar to 12 bar.
- QUESTION: What size tank inlet do I need to fit the Hansen Fast-Flo Valve and Hansen Mini Fast-Flo Valve?
- ANSWER: All Hansen float valves carry a 25mm (1”) female thread on the valve inlet. This gives you a couple of benefits. The valve will fit inlets from 15mm to 50mm when using our range of adaptors. The additional material used at the inlet to form the female thread strengthens the valve at an area that has been identified as a weak point in other brands of valves.
- QUESTION: What temperature can I use Hansen fittings at?
- ANSWER: Hansen have tested all its products for use with cold water up to a maximum temperature of 60°C (140°F). We do not recommend the use of these products with temperatures higher than 60°C (140°F) as plastic expands due to temperature increases. Hansen cannot guarantee the products will perform when used with temperatures over 60°C (140°F). Hansen products that have failed in temperatures higher than 60°C (140°F) will not be covered by our Hansen Warranty.
- QUESTION: What type of thread sealant should I use?
- ANSWER: Use a thread sealant on all threaded connections. It is recommended to use Loctite 5331.
- QUESTION: Will the Hansen Fast-Flo valve work in my calf shed bowl troughs
- ANSWER: Yes, the Fast-Flo was designed as a compact valve for use in small bowls, compact troughs, feeders & header tanks or any situation where the valve space is confined.
- QUESTION: Will the Hansen Mini Fast-Flo valve work in my calf shed bowl troughs?
- ANSWER: Yes, the Mini Fast-Flo was designed as a compact valve for use in small bowls, compact troughs, feeders & header tanks or any situation where the valve space is confined.
- QUESTION: Will the higher flow cost me more to run my pump?
- ANSWER: No, because the Hansen Super-Flo valve is more efficient than what you are used to. The reduced operating pressure required will equate to higher flows at lower pressures at your pump which in turn will reduce pumping time and cost.
